I'm unsure about whom else you've interviewed, but the position as I see it is as such (named challenges). The experience I'm bringing to the table relates to those problems through the following exposures and experiences (named solutions I've worked relating to those challenges). I feel my experience at (project 1, project 2 and project 3) all relate to your current challenge, and in addition to my specific language skill (fluency in the requested language) make me a viable candidate for this position.
